Step 1: Rate – The normal range of heart rate is between 60 and 100 beats per minute.Bradycardia is present if the rate is less than 60 beats per minute andtachycardia is present if the rate is greater than 100 beats per minute.

Step 2: Rhythm – Locate the P waves. All leads should be examined for P waves. The absence of P waves may denote atrial fibrillation. Establish the relationship between P waves and the QRS complex. The number of P waves should equal the number of QRS complexes. If there are more QRS complexes than P waves, then the rhythm is an accelerated ventricular or junctional rhythm. If there are more P waves than QRS complexes, then AV block is present. If P waves occur after each QRS complex consider: junctional rhythms, ventricular rhythms with retrograde AV conduction, an AV nodal reentrant rhythm or AV reciprocating tachycardias.

Step 3: Axis – Determine normal axis, left axis deviation or right axis ...
